Abstract
An automated circuit board tester comprises an unstacker (1) arranged upstream of a testing device and which by means of a circuit board picker (40) arranged above a chute (30) picks a top-most circuit board from a stack of circuit boards (55) located in the chute (30). The chute (30) comprises a lifting device including at least two sets of vertically travelling supporting elements (38, 101), each of which is able to carry a stack of circuit boards (55). The chute (30) is open at least on one side so that a set of supporting elements (38, 101) can be loaded while a stack of circuit boards (55) located on the other set of supporting elements (38, 101) is unstacked by the circuit board picker (40).
